The Agilent/Keysight 8769K is a Single Pole, Six Throw (SP6T) multiport coaxial switch delivering reliable RF signal routing from DC to 26.5 GHz. Built on proven solenoid-driven switching technology, it combines low insertion loss with exceptional port isolation across the frequency spectrum. The 8769K executes switching in less than 20 milliseconds and sustains over 5 million cycles per port, making it ideal for automated test equipment, signal distribution, and RF monitoring systems requiring precise, repeatable switching with minimal signal degradation.
